IMPRovED HINGEf l Specification forming part of Letters Patent N0.50,41l, dated :October l0, 1865.

To all whom it may concern:

Be it known that: we, HENRY YOUNG and MARTIN STAGHELIN, ot' PortChester, in the county of Westchester and State ot' New York, haveinvented a new and Improved Hinge and we do hereby declare that thefollowing is a full, clear, and'exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure l represents a sectional front elevationof this invention. Fig. 2 is a transverse section ot' the same, the line:c x, Fig. 1, indieating the'plane of section. Fig. 3 is a longitudinalcentral section of the saine when the two wings ot' the hinge are placedin a position at right 'angles one to the other.

Similar' letters of reference indicate like parts.

This invention relates to a hinge, the two wings ot' which swing on ahollow spindle through which a bar of steel or other suitable materialpasses, the ends ot' which aresecured in plugs, one ot' which isfastened to one and the other to the other ofthe wings of the hinge insuch a manner that the hinge swings freely in either direction; and. atthe saine time, by the torsional power of the steel rod, said hinge isalways brought back to its orignal position of rest, and, consequently,if a dooris hung on a pair otl these hinges itwill open in either.direction and be self-closing.

A represents a hinge, the two wings B C of which swing on a hollowspindle, D. Through this hollow spindle passes a bar, E, of steel or anyother suitable elastic material, at, round, or ot' any other suitableshape, and the ends ot' this bar` are secured in plugs F G, the plug Fbeing rigidly attached to the wing O, and the plug G tothe wing B of thehinge by screws a door-spring with the hinge, and the spring which weuse is so constructed that it acts with equal force in either direction,and that it .is

not liable to looseits power, since what islost in one direction isgained in the other.

lBy turning the plugs F G in their sockets the power of the spring canalways be regulated, and a hinge is obtained which serves lor doors otlany description. v

When the hingeis to be used foradoor which 'opens both 'ways the bar Eis so adjusted that the normal position ot' the two wings is that shownin Figs. l and 2 ot' the drawings, and by releasing the plug in one otthe wings said wing can be readily adj usted for a right or for 4a lefthanded door.

' Wve do not claim, broadly, as our invention the application ot' aspring: to a hinge, such having been previously done; but

We claim and desire to secure by Letters Patentj 1 The hollow spindle D,bar E, and plugs F G, in combination withthe. two wings of a hinge,substantially as andfor the purpose set forth.

The above specification of oui` invention signed by us this 8th day ofAugust, 1865.
